synthesis of D- and L-N-(4-amino-3, 3-dimethyl-2-hydroxybutyryl)- β-alanine (7) is described. Compound 7 is an analog of pantothenic acid in which the 4′-hyroxy group is replaced by amino group. The synthetic sequence leading to 7 involved the synthesis DL-4-amino-3,3-dimethyl-2-hydroxybutyric acid and its resolution. Coupling of N-benzyloxycarbonyl N-hydroxysuccinimide ester (5) with β-alanine and followed
描述了D-和LN-(4-氨基-3,3-二甲基-2-羟基丁酰基)-β-丙氨酸的合成(7)。化合物7是泛酸的类似物,其中4'-羟基被氨基取代。导致7的合成序列涉及DL-4-氨基-3,3-二甲基-2-羟基丁酸的合成及其拆分。将N-苄氧基羰基N-羟基琥珀酰亚胺酯(5)与β-丙氨酸偶联,然后除去保护基,得到7。
